有教无类。

　　In teaching there should be no distinction of classes.

　　当仁，不让于师。

　　When it comes to benevolence, one need not give precedence even to his teacher.

　　我非生而知之者，好古，敏以求之者也。

　　I am not one who was born in the possession of knowledge; I am one who is fond of antiquity, and earnest in seeking it there.

　　三人行，必有我师焉。择其善者而从之，其不善者而改之。

　　When I walk along with two others, they may serve me as my teachers. I will select their good qualities and follow them, their bad qualities and avoid them.

　　学如不及，犹恐失之。

　　Learn as if you could not reach your object, and were always fearing also lest you should lose it.
